GABBERT BUTTE NATURE PARK Hello,Gresham We’Re Parks Metro and Trails GABBERT BUTTE NATURE PARK Hello,Gresham We’re parks Metro and trails The second-largest city in the Portland metropolitan area, Gresham is home to just over 108,000 residents DRAFT 10-3-2016 and diverse natural features, including wetlands, riparian areas, forested uplands and buttes. Over the last 150 years, Gresham’s landscape has changed from a quiet berry-farming community to a busy city with a wide variety of neighborhoods. Today, one of the most noticeable vestiges of the forestry and agricultural economy that remain are the upland open space buttes. Open space preservation Gresham has a long history of public support for protecting its diverse natural features. The earliest Gabbert Butte preservation and park planning dates back to the 1990 City of Gresham Open Space Bond Measure, where Gresham voters approved $10.3 million in general-obligation bonds to purchase park sites, wetlands, buttes, greenways and creek corridors for preservation. Significantly, Gresham’s was the first open-space bond measure approved by any community in the Portland metropolitan area. Restoration Throughout the city, restoration work is helping to improve water quality, minimize erosion and property loss, reduce flood damage and boost diversity of plant and animal life. Restoration projects in natural areas help return the ecosystem to a healthy, functioning condition. In the East Buttes, the city has focused restoration efforts on removing invasives and planting native plants. Restoration of City owned land near Butler Road included planting 5,000 forbs, rushes, shrubs, and trees.

Upland forest water cool and clean upstream. A mix of conifers and deciduous trees covers the East Buttes. Upland forests like this are common in the Pacific Northwest, but in urban areas forests have been fragmented and removed by the growth of cities. The lands protected in the East Buttes preserve core areas of upland forest within a developing area.

Over the past 15 years, and with help from volunteers, the City has completed restoration of approximately 20 acres on Gabbert Butte. A nearby effort includes a large area of holly removal from a former holly farm on Gresham Butte. Ivy removal at Butler Creek Volunteer restoration event Oregon Slender Salamander Years of work by City staff has documented Oregon Slender Salamanders in the East Buttes including on Gabbert Butte. Prior to their discovery here, they had not been found west of the Cascades. The Oregon Conservation Strategy considers Oregon Slender Salamander a sensitive species. They like moist places inside large decaying logs or under slabs of bark that have fallen off of snags. Oregon Slender Salamanders are lungless and breathe through their skin! Flying Squirrels Have you seen nesting boxes on some of the trees at Gabbert Butte? The nesting boxes were installed to support northern flying squirrels. The flying squirrel doesn’t actually fly, it glides from tree to tree. These animals typically nest in large holes in trees and eat fungi and lichens, as well as seeds, nuts, insects, bird eggs and nestlings and conifer cones. Flying squirrels are seldom seen because they are nocturnal. photo: Oregon Dept. of Fish & Wildlife photo: Caters news agency GABBERT BUTTE NATURE PARK Volcanoes and floods DRAFT 10-3-2016 Lava domes Gabbert Butte is part of the Boring Volcanic Field, which contains more than 80 small volcanic vents and lava flows. These eruptions were caused by the Juan de Fuca Plate sliding under the North American Plate. Each lava dome erupted just once, and thick, slow-moving magma created buttes that we see today. The first eruptions began about 2.5 million years ago, and between 1.3 and 1 million years ago, the active field was widespread. The existing lava domes are now extinct, but some believe that the boring lava field is not. Don't worry, the likelihood of an eruption is very low! Towle Butte The youngest volcano, Floods Beacon Rock, erupted about 57,000 years ago, About 15,000 years ago, the lands surrounding the buttes and then the Missoula were flooded repeatedly, when ice dams gave way and Floods scoured away the emptied glacial Lake Missoula. The Missoula (or Bretz) cinder cone, leaving just its Floods covered the valley floor with hundreds of feet of central plug. water. Rich farmland resulted from soils washed into the valley by the floods.

  • Natural Areas Restoration Plan October 2010
    Natural Areas Restoration Plan October 2010 Update: March 2015 Natural Areas Restoration Plan Update March 18, 2015 Portland Parks & Recreation (PP&R) completed the first system wide Natural Areas Restoration Plan (plan) in October 2010. The plan was completed as a requirement for Salmon Safe certification. It established restoration goals and strategies, management priorities and implementation actions. It is currently used to set restoration priorities (staff effort and funding) for natural areas. The plan stated that there would be a review and update every 3-5 years. The 2014 update modified the functional methodology and revised the weighting to remove the emphasis on salmonids and their habitat needs. The 2014 Natural Area Management Priority Matrix changes are based on the updated natural resource function methodology and ecological health determined by the best professional judgment of the ecologist managing the site. The goals, strategies and implementation actions remain the same. This updates also includes the natural area properties purchased since 2010. Methodology Update The methodology update evaluated additional functions and created a new weighting system. The original plan weighted functions associated with salmon habitat the highest while this update does not. Some of the updated functions were assigned weighted scores on a scale of 3 (high) to 1 (low) similar to the scoring used in the 2010 plan. A natural area was also given points for Terrestrial Ecology Enhancement Strategy (TEES) special status habitats and City of Portland At-Risk Species. The functions included are: (see attached memo for details): Streams: Perennial, non-perennial and within 100 feet of the natural area.

They protect headwater streams that feed these rivers, including a significant part of Johnson Creek’s watershed. The Connect with The region’s most urban stream, Johnson Creek is a focus of salmon and lamprey recovery and the forests in the East Buttes Nature initiative led are critical to this effort.

  • Portland Harbor RI/FS Final Remedial Investigation Report February 8, 2016
    Portland Harbor RI/FS Final Remedial Investigation Report February 8, 2016 3.0 ENVIRONMENTAL SETTING This section describes the current and historical physical characteristics and human uses of the Portland Harbor Superfund Site (Site). Physical characteristics of the Site include meteorology, regional geology and hydrogeology, surface water hydrology, the physical system (which includes bathymetry, sediment characteristics, and hydrodynamics and sediment transport), habitat, and surface features. Human characteristics of the Site that are discussed here include historical and current land and river use, the municipal sewer system, and human access and use. In addition to providing context to the RI sampling and analysis, the factors presented in this section are considered in the refinement of the study area-wide CSM, which is presented in Section 10. Section 3.1 focuses primarily on the physical setting within the study area (RM 1.9 to 11.8). However, the physical features of the Willamette River from Willamette Falls (RM 26) to the Columbia River (RM 0), as well as the upstream portion of Multnomah Channel, are discussed as needed to place the study area’s physical characteristics into a regional context. The Willamette River basin has a drainage area of 11,500 square miles and is bordered by foothills and mountains of the Cascade and Coast ranges up to 10,000 ft high to the south, east, and west (Trimble 1963). The main channel of the Willamette forms in the southern portion of the valley near Eugene, at the convergence of the Middle and Coast forks. It flows through the broad and fertile Willamette Valley region and at Oregon City flows over the Willamette Falls and passes through Portland before joining the Columbia River (Map 3.1-1).
